IMPROVEMENT lN WATCHMENS TIME-DETECTERS.

Specification forming part of Letters Patent No. 156,098, dated October20, 1874; application filed September 19, 1874.

To all whom it may concern:

Be it known that I, ANTON MEYER, of Stuttgart, Wurtemberg, Germany, haveinvented a new and Improved Watch m ans Time- Detecter, of which thefhllowing is a specification:

In the accompanying drawing, Figure 1 represents a top view of myimproved watchmans time-detecter, with lid thrown open to show interiorconstruction; and Fig. 2 is a partial vertical transverse section of thesame on the line 0 c, Fig. 1, showing arrangement of the markingdevices.

Similar letters of reference indicate corresponding parts.

My invention relates to improvements in watchmens time-detectors, bywhich the printed dials hitherto in use may be dispensed with and plainpaper disks be substituted, on which the marks of the stations and thetime are quickly printed, with or without colors, by suitable springdevices without the direct action of the keys on the marking parts and abridge-piece. My invention consists of a rotating steel dial, which hasthe hour and minute subdivisions engraved in raised figures thereon, andis set in motion by a suitable clock-train. The numbers of the stationsare arranged sidewise thereof and marked on a plain paper disk, rotatingwith the steel dial, by means of strong band-springs with steelmarking-plates, which are actuated by the keys at the stations in such amanner that one spring strikes on the steel disk at each station forindicating the time, while the springs for marking the stations striketheir corresponding numbers consecutively in the customary manner.

A represents the casing or box of my improved watchmans time-detecter,which is made in the usual style for being securely locked. Aclock-train for rotating the central steel dial B is arranged in thebody of the easing, while the springmarking devices 0 are attached insuitable manner to the lid D. The steel dial B has the figures of thehour and minute subdivisions engraved thereon, the steel dies E formarking the numbers of the stations being secured sidewise of the steeldial, as many dies being provided as thereare stations to be visited bythe watchman. A plain paper disk, B, is securely fastened by means ofgrooved pins a to steel dial B for rotating therewith, being largeenough to extend over the steel dies for marking the stations. Themarking devices 0 are made of strong V-shaped steel band-spring 0,provided with small solid marking-plates d and curved or taperin g ends0, which are arranged sidewise of the barrel-guiding pin f attached to asupporting-plate, f, of lid D, so that the key, when placedv thereon andturned, engages the curved ends of the springs, presses them back, andallows them to strike with considerable force with their marking-platesd on the steel dial and dies, embossing thereby the time and number ofstations on the interposed rotating disk. The marking-springs U areplaced sidewise of each other, the innermost being stronger than theothers and placed above the raised time-figures at the circumference ofthe steel dial B. All the keys are provided with end wards for actuatingthis time-1narking spring at every station, while the wards foractuating the station-marking springs are arranged in changing positionsthereon for producin g the consecutive action of the same, and therebythe true record of the watchmans visits at thestations. The marks can bemerely embossed, as described, or be printed in colors, as desired.

This detecter has this great advantage over the time-checks requiringprinted dials, that anybody can make the disks, and, further, that themarks are clearly produced by the instant strokes of the springs withoutinterference with the regular motion of the steel dial and clock-train.Hitherto the marks were made by keys pressing the marking devices on thepaper dials and against a bridge, or pressing directly the paper dialsagainst the marks; but paper dials and bridge are by the springmarkingof the keys dispensed with, and thereby the usefulness of thetiine-detecters improved to a considerable extent.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. As an improvement is watchmans timedetecter, a rotating steel dialwith raised time indicating figures for imprinting on a plain disk thetime of visiting any station, substantially as specified.

2. In awatchmans time-detecter, the combination of a rotating steeldial, station-marking steel dies, and plain disk, with strong steelsprings with markingplates actuated by the keys at the station forimprinting the time and number of stations on the disk, substantially inthe manner and for the purpose set forth.

3. The combination of a marking-spring, actuated by the keys at everystation, with a number of station-marking springs arranged therewith, tobe actuated in consecutive order as the stations are visited,substantially as described.

4. In Watchmans time-check, the marking band-sprin gs, havingstriking-plates d and curved ends 0, for being engaged by the keys forstriking the marking-dies, as set forth.

The above specification of my invention signed by me this 4th day ofAugust, 1874.

ANTON MEYER.
